Dishonest, ignorant or lazy?
I can't decide which of these best describes large portions of this article.
Let's start with "Renewables simply aren't cheaper than fossil or nuclear. That, after all, is why we live in a fossil and nuclear powered world". Hmm, that is a very interesting analysis.
Would it be fair to say that fossil fuel genration has been subsidised, both directly to maintain jobs in the extraction industries and indirectly by allowing the externalisation of the majority of the environmental costs.
And that was the difficult one. Nuclear has received unimaginable amounts of (global) government hand outs. In the early days, the nuclear power industry was the poster child used to hide - things like the primary reason for Calder Hall and Chapelcross was to produce weapons grade plutonium. Even today we see that while a private nuclear operator may have to pay the majority of costs of construction and operation of new nuclear build, the major costs (waste management, insurance and decommisioning) appear to be a burden for the public purse.
Yes, renewables have received susidies too but these are virtually negligible compared to the sums pumped in to nuclear.
Now lets look at
"A modern nuclear powerplant can sustain more than three quarters of a million electro-European future citizens. If a seven-billion-strong human race lived at that standard, there'd be a need for approximately 10,000 such plants, which could be located anywhere. (There are already many more power stations than that in existence. We are talking about less infrastructure than now, not more.) There'd no longer be a need for any world-spanning supergrid or massive redundant backups or new transport routes across the Sahara, etc."
Now if the author was an expert on nuclear power he would be aware that an LWR is taken completely off-line, for 2-3 months, every 3 years for re-fuelling. So at any time, you are looking at 1 in 12 reactors producing zero power so you need to provide a guaranteed 8% over-capacity in the local grid. And god forbid a reactor scram, something that can take a reactor 2 days to recover from - so you need local (non-nuclear) over-capacity... or some kind of super-grid?
I'll just pick at the low hanging fruit that haven't been pointed out already.
